I have the code below to handle numeric. I have similar CASEs to handle other types. But now I have this to parse:

W9N

Which means that the output must have a "W" for the first character, followed by 9 numeric values. How can I handle these types of things?

		CASE INLIST(FieldVal,'N')
			* Numeric
			FormatValue = 'N'
			FieldLength = CHRTRAN(FieldValue, FormatValue,'')
			FieldType = CHRTRAN(FieldValue, FieldLength,'')
			IF FieldLength = 0
				FieldLength = 100
			ENDIF
